Review: Tube Audio Design TAD-60 Tube amp


Category: Amplifiers

I'll start by saying that I've been into higher-end audio for a few decades now, and quite a lot of equipment has been through my hands to this point (half the fun of this hobby). Somewhere around 12 years ago, I'd come to realize that I preferred tube amplification over solid state in terms of an overall involving presentation of the music, and ever since then have owned tube stuff (brief flirtations with various solid state devices only helped to enforce this notion).

Which brings me to the discovery of Tube Audio Design, the provider of components conceived by Paul Grzybek (of Bizzy Bee Audio fame), built to his specifications by a very reputable Chinese manufacturer, and then hand-finished by Paul in his shop located in Wheaton, IL. (His offerings are available exclusively online; detailed product info is found at http://www.angelfire.com/biz/bizzyb/index.html)

The TAD-60 amplifier is built like the proverbial tank; overall appearance and heft (not to mention its specifications) in my experience indeed belie the modest asking price. With its stainless steel chassis and almost 1/2"-thick black anodized face, the relatively compact package portrays a masculine but elegant stance (also included is a lift-off stainless steel tube cage). All function controls are easily accessible from the chassis top, as are the tube bias test-points and adjustment pots (a digital voltmeter is included too).

EL34-based, the TAD-60 is rated at 60wpc in UL-mode, and 30wpc in switchable-on-the-fly triode-mode. Other standard features include adjustable input sensitivity and adjustable global feedback, adding flexibility to a host of possible preamp and speaker combinations (the input sensitivity control may also be used as a volume pot in a single-source direct input configuration).

Listening to the TAD-60 after the recommended 30 hour break-in period and beyond, the music really began to open up, and along with the TAD-150 preamp, I was experiencing just about every CD I spun in a whole new manner - I'm particular to small-ensemble jazz and female vocals - there was an in-the-room conveyence of the music that I found startling at times - present is deep, tight bass, a glorious midrange, detail, depth, and an overall natural presentation that allows hour after hour of enjoyable listening. I've found that the feedback adjustment permits a fine-tuning of balance between dynamics and warmth, and was able to "lock in" the amp to my speakers for what sounds to be a perfect sonic match (just a tad of feedback along with the triode-mode setting seems to be the magic spot in my case).

Without attempting to describe every sonic attribute I'm hearing (though I'm happy to answer any particular inquiries), suffice it to say that the TAD-60/TAD-150 combination strikes a synergy and glow that is especially musical, and is among the finest I've had the pleasure of owning. The TAD-150 has already been highly praised in at least a few user and online reviews, and I bet the TAD-60 will soon be recognized as a similar standout. If you happen to be in the market for high quality, reasonably priced, excellent-sounding gear, just take a listen for yourself, and you will hear what these components can do for music. (Paul also offers a 15-day in-home trail period.)

Note: I have no financial interest or business relationship with Paul Grzybek or Tube Audio Design.

Perkadin: I believe the two models are each provided by a different manufacturer, so there's one explanation. Paul had mentioned a while back that he could get ahold of an optional black faceplate for the TAD-150, but I think the setup looks just fine the way it is - I wondered about a visual match as well before actually seeing the two pieces together, and as it turns out, in person the setup really does come off very nicely. In any event, what matters most to me is the glorious sound that this pair produces.
I own the TAD-60 and TAD-150 Signature combo and I agree with the review. These are wonderful sounding pieces. They are also very well made made and I like the look. Highly recommended!!
Has anyone made any direct comparisons with the cayin Ta-30 which I have paired with the Tad-150 I would imagine the Tad-160 would have better dynamics due to the increased pwr rating but just wondering if there any other differences to note.

Having owned both the TAD 60 and TAD 150 for about a month, I'd like to chime in about these wonderful tube beauties. I've been in high end audio for thirty years and have owned lots of both tube and transistor units, What the Tube Audio Design pieces remind me of are the early Conrad-Johnson classics of the mid 70's. Back then the PV-2 and MV-45 combo was a warm musical experience that was pleasing to both your ears and your wallet. These TAD creations from Paul Grzybek are detailed, tight, warm and smooth. They offer some great features for the money as well, like a remote(150) amd variable negative feedback(60). As previous fans mentioned, they are built like tanks and have the fit and finish of "Salon" equipment. So what you get ultimatly are, new classic tube gear that give you the C-J type sound but are faster, quieter and affordable.
As Finrok points out, the sound is very much like the CJ offerings, which I surmised and instead of purchasing the CJ CAV-60 ($1500 used), I went with the TAD-60. I couldn't be happier.

I've only run mine for about 20 hrs, so commenting is a bit premature, but the sound is detailed, tight, warm and smooth as previously mentioned. I'm running it with a Bottlehead Foreplay III and the sound is simply exquisite and this combination can drive even inefficient speakes.
